Non-standard reducers are mainly used in special pipeline transition scenarios that cannot be adapted by various standard pipe fittings, solving problems such as mismatched diameters, incorrect taper, insufficient wall thickness, and struct
Inquiry
When the on-site pipeline diameter, taper, wall thickness, or connection structure does not match standard pipe fittings, non-standard reducers are custom fittings used to solve this type of transition problem. We can design and machine them individually according to drawings, dimensional parameters, and working condition requirements provided by the customer. Structurally, concentric or eccentric types are available. Processes include seamless hot pressing, steel plate rolling and welding, and forging. Materials can be carbon steel, stainless steel, alloy steel, wear-resistant materials, and insulation composite materials. Customization is supported for special wall thicknesses, extremely large diameter reduction differences, extended sections, special tapers, irregular ports, and more. The products are mainly used in industrial technical transformation, old pipeline renovation, special equipment, mining, metallurgy, environmental protection, powder conveying, and other scenarios. Before purchasing, it is recommended to provide diameter, wall thickness, length, taper, pressure and temperature, and connection method, and we will confirm the processing plan and quotation accordingly.

Customizable length and taper: can customize short-section type, extended section, ultra-long taper, gentle taper, sharp taper special structures, meeting the working conditions of narrow spaces and ultra-long transitions. Pressure adaptation range: 0.6MPa—100MPa, can customize normal pressure, medium pressure, high pressure, and ultra-high pressure non-standard structures. Temperature adaptation range: -196℃ low temperature to 650℃ high temperature, adapting to deep cooling and high-temperature overheating special media. Material parameters can be freely matched with carbon steel, stainless steel, alloy steel, duplex steel, wear-resistant steel, and rubber-lined and plastic-lined composite materials. End |
| Customization | Our factory possesses super strong non-standard customization capabilities across all categories, all structures, and all working conditions, and can undertake processing orders for all difficult and special-shaped reducing pipe fittings. It is a professional source factory for non-standard pipe fitting customization in the industry. Supports customization of any non-standard size, covering special diameter combinations, special long and short straight pipe sections, unconventional eccentricity, special tapers, special-shaped grooves, and long and short section special-shaped structures. Supports customization in all materials; carbon steel, stainless steel, alloy steel, duplex steel, heat-resistant steel, wear-resistant steel, and plastic-lined and rubber-lined anti-corrosion composite materials can all be customized. Supports customization in all processes, with full coverage of seamless hot pressing, rolled welding, forged machining, overall precision machining, and internal and external precision shaping processes. Supports customization for special working conditions, including high-temperature resistance, high-pressure resistance, low-temperature resistance, wear resistance, corrosion resistance, explosion-proof thickening, and anti-static special non-standard redu |
| MOQ | Non-standard reducers adopt an ultra-low-threshold flexible customization minimum order mode, fully adapting to various needs such as engineering replacement parts, drawing samples, small-batch technical modifications, and large-batch complete-set projects. For all conventional non-standard sizes and conventional carbon steel and stainless steel material products, the MOQ is as low as 1 piece, with no minimum order quantity restriction, supporting single-piece drawing customization, sporadic maintenance replacement parts, and engineering trial assembly and sample procurement, solving customers' small-quantity |
| Lead Time | The factory has a complete non-standard pipe fitting customization production line, covering the full processes of hot pressing, rolling, welding, machining, flaw detection, and anti-corrosion, with stable and controllable delivery times, efficiently responding to domestic and international non-standard customization orders. For simple-structure non-standard reducers, conventional materials, ordinary sizes, and products without complex process requirements, the production cycle is 3-5 working days, quickly meeting customers' needs for engineering emergency repairs and technical modification replacement parts |
| Packaging | Because the sizes, specifications, and weights of non-standard reducers are not uniform, customized classified export packaging solutions are adopted to eliminate problems such as collisions, deformation, paint loss, and rusting during transportation of special-shaped products. Small non-standard special-shaped pipe fittings are uniformly wrapped in multiple layers of bubble film, with dust-proof sealing at the ports and independent shockproof wrapping, packed into reinforced export cartons, with separate labels distinguishing drawing numbers and batches. Medium-sized non-standard reducers are wrapped in double layers of waterproof woven fabric, with customized protective rings added at the ports and thickened anti-collision treatment at the corners, avoiding wear during transportation of special-shaped structures. Large-diameter extra-large non-standard rolled pipe fittings and heavy thick-wall customized products are fixed with solid wood fumigated pallets, reinforced with steel straps, and sealed with overall wrapping; the pallets comply with import and export quarantine standards and can clear customs directly. All special-shaped products are individually numbered and archived corresponding to drawings |

Non-standard reducers are custom-produced according to drawings and working condition parameters, with no fixed standard parameters. When inquiring, please provide diameter, wall thickness, length, taper, pressure and temperature, material requirements, and connection method. If you have drawings, provide the drawings directly. If you do not have drawings, you can provide on-site measured dimensions. Our engineers will assist in confirming the plan before arranging production. For conventional non-standard sizes and products made of conventional carbon steel and stainless steel materials, the MOQ is as low as 1 piece, supporting single-piece drawing customization and project replacement parts. For products with simple structures, conventional materials, and ordinary sizes, the production cycle is 3-5 working days, and for complex large-diameter thick-wall styles, it is 8-12 days. Packaging is handled by category according to product size and weight. Small parts are wrapped in multiple layers of bubble film and packed in reinforced export cartons. Medium-sized parts are wrapped in two layers of waterproof woven fabric and fitted with port protection rings. Large-diameter heavy-duty parts are fixed on solid wood fumigation pallets and reinforced with steel straps, suitable for long-distance sea, land, and air transportation.
We provide one-on-one drawing coordination services for customized customers. Before sales, pipeline engineers review the drawings, assist in optimizing the structural process, and check dimensional parameters to reduce the risk of rework caused by drawing errors. During production, we synchronize the progress of cutting, machining, welding, flaw detection, shaping, and other stages, and can provide production live-action videos and process materials. After sales, we provide an 18-month warranty. During the warranty period, for quality problems not caused by human installation errors, we will rework and remake free of charge, resend products, and bear logistics costs. For installation adaptation issues, we provide remote technical guidance and pipeline connection debugging support, and the after-sales team responds online 24 hours a day.
